Anthropology and Human Modernity

Article / Updated 12-13-2021

Modern humans have physical and behavioral differences from ancient humans. When you're studying anthropology — specifically, modernity in humans — keep these points in mind. They highlight the most important characteristics of anatomical and behavioral human modernity: Anatomical modernity is having anatomical characteristics indistinguishable from modern, living humans. Appearing by 100,000 years ago, these characteristics include a larger brain (averaging 1,450 cubic centimeters), a larger body overall, and the presence of a chin. Behavioral modernity is behaving in ways that are indistinguishable from modern humans; it appears by 100,000 to 50,000 years ago and includes symbolism (the use of one thing to represent another thing), complex language (with complex grammar), and complex tool use (such as the use of symmetrical tools). Modern humans colonized sub-Himalayan East Asia by 80,000 BP (before present, a term archeologists use), Southeast Asia and Australia by 40,000 BP, Europe at least by 30,000 BP, the New World by 14,000 BP, and the Pacific and Arctic by 1,000 BP.

Anthropology For Dummies Cheat Sheet

Cheat Sheet / Updated 12-13-2021

What is anthropology? The study of humanity, or anthropology, starts with the origin and evolution of humanity. Other elements key to the study of anthropology are human modernity (anatomical and behavioral); defining culture and cultural universals; how humans feed themselves (subsistence) and the influence of subsistence on social organization; and human language.

How Anthropologists Group the Early Hominids

Article / Updated 12-13-2021

By studying early hominids (large, bipedal primates) that date back to millions of years, anthropologists can track the development of the human race. When exploring anthropology, keep these important points in mind: The evolutionary process shapes species by replication, variation, and selection, leading to adaptation. Humans are one of roughly 200 species of the Primate order, a biological group that's been evolving for about 60 million years. Hominids appear (only in Africa) by at least 4 million years ago with the following adaptive characteristics: bipedalism (habitually walking on two legs), encephalization (larger brains than expected for their body size), small teeth (smaller teeth than expected for their body size — the canines in particular). The following table summarizes what anthropology has discovered about the main groups of early hominids. Hominid Group, Diet, and Tool Use Some Genera and Species Included Fossil Finds Dates Evolutionary Fate Gracile australopithecines: omnivorous diet with little tool use Australopithecus afarensis, Australopithecus africanus A. afarensis in Ethiopia, and A. africanus at many sites in South and East Africa Over 4 million years ago (A. afarensis) to about 2 million years ago (later A. africanus) A. afarensis probably ancestral to A. africanus; A. africanus probably ancestral to early Homo Robust australopithecines: more herbivorous diet with little or no tool use. Australopithecus aethiopicus, Australopithecus robustus A. aethiopicus and A. boisei in East Africa, A. robustus in South Africa Over 2 million years ago (A. aethipoicus) to about 1 million years ago (late A. robustus) Extinction around 1 million years ago Early Homo: omnivorous diet with more animal tissue consumption and survival relying on tool use. Homo habilis, Homo rudolfensis, earliest Homo erectus Olduvai Gorge, Tanzania and Koobi Fora, Kenya Earliest Homo around 2.5 million years ago; clearly H. erectus by 1.8 million years ago Evolved into H. erectus by 1.8 million years ago

Culture and Cultural Universals in Anthropology

Article / Updated 12-13-2021

Anthropologists don't just study the evolution of human beings; they also learn about their cultures, how cultures develop, and how cultures shape human behavior. If you need to refresh your memory about culture, like what it is and how it guides human behavior, take a look at these aspects: Culture is a learned set of ideas and rules about appropriate behavior shared by a group; it's passed on from one generation to the next not by the genes but with language. Although the contents of each culture are different, each culture has specific ideas of language (a way to communicate), ethics (concepts of right and wrong), social roles (rights and responsibilities per gender and age class), the supernatural (the realm of supernatural beings), styles of bodily decoration (styles normally indicate identity), family structure (marriage customs and rules for inheritance), sexual regulation (incest taboos and marriage customs) and food preferences (ideas of what's appropriate for consumption at various social gatherings).

Worldwide Distress Frequencies and Phone Numbers

Article / Updated 04-26-2016

To call for help in an emergency situation, you can use any radio transmitter you have access to, and you can tune it to any frequency to call for help. When in need of rescue, the law gives you unlimited access to radios and their frequencies. However, you’re much more likely to get a faster response if you send a distress signal on a distress frequency. The following is a list of the radios you’re likely to run into and distress frequencies used in different parts of the world: VHF Radio: Channel 16 CB Radio: Channel 9 Family Radio Service (FRS): UHF: Channel 1 Single-sideband and amateur (ham) radio: 2182 kHz, 14.300 MHz, 14.313 MHz Air band Radio: 121.5 MHz, 243MHz UHF Radio (Australia): Channel 5 Cellphones: Try dialing 911 on your cellphone, even if you think you’re not within coverage. Then try texting someone who you know checks his texts. Text is better than voice in many cases because it can get through when voice can’t. If you have plenty of battery power, send a text, and then leave the unit on as you travel. The unit searches for reception until it transmits. The higher you are, the greater the possibility that your cellphone will make contact with a tower. 911: U.S., Canada, Central America (partial), Philippines 066, 060, 080, 911: Mexico. 112: Europe, Australia, New Zealand, Colombia, India, South Korea, South Africa, Israel 999, 120: China (PRC) 110: Jamaica 190, 191: Brazil 1669, 191: Thailand 113, 115: Vietnam, Chile SOS in Morse code: . . . - - - . . . (3 short tones, 3 long tones, 3shorts) International distress signal code word: Mayday, spoken three times

Methods for Signaling Search-and-Rescue Teams

Article / Updated 04-26-2016

When you’re in the wild and need help, you send out a signal –- basically anything to get noticed. A good signal not only gets the attention of search-and-rescue teams but also of people not looking for you — passersby who can help before professionals arrive. The following methods show you how to get people’s attention with signals. Ground-to-air emergency code These symbols are recognized by Search and Rescue pilots as distress signals. Make sure you make these signals a 6:1 ratio so rescuers can see them from the air. Aiming reflector You must carefully aim your mirror’s reflection at the aircraft or vessel you wish to signal, or you may not be seen. You can use a mirror or other reflective items, such as a CD or DVD. Group splash If a ring of people all kick simultaneously, the water in the center turns white, briefly, which can be seen against the blue ocean.

Improvising Navigation in the Wilderness

Article / Updated 04-26-2016

Using the sun, the stars, and a little ingenuity can help you find your way in the wilderness and is easy to do more often than not. Remember, people have been using the heavens to navigate for thousands of years. The following techniques can be used anywhere on Earth and are sometimes incredibly accurate, but give you only general direction: Stick and shadow Plant a long stick in the ground and mark the tip of its shadow. Wait 15 minutes and mark new spot. This is the east-west line. Put your left foot on the first mark and your right on the second. You’re facing due north. The North Star The North Star is located between the Big Dipper and Cassiopeia. This method for finding North is always exact. When you’re facing the North Star, west is directly to your left, east, to your right, and south behind you. The Southern Cross The Southern Cross lies between the two Pointer Stars and The False Cross. The Southern Cross points perfectly south only when it’s standing straight up. Otherwise, use an imaginary point to estimate due south, as the figure shows:

What Is Linguistic Anthropology?

Article / Updated 03-26-2016

Language is the system humans use to communicate. Linguistic anthropology studies human language, and these points highlight humanity's distinct way of transmitting information: Human infants aren't born with language already in mind, but all healthy infants are born hard-wired to acquire any of the uniquely complex rules (grammar) of any human language. Each language has a unique grammar, a complex set of rules that tell how to properly order the words in a sentence; children normally learn the outline of this grammar by about 3 years of age.

Anthropology of Subsistence and Social Organization

Article / Updated 03-26-2016

Humanity has practiced all kinds of ways of subsistence, or getting food. This table shows different modes of subsistence and the affects they've had on social organization. Band Tribe Chiefdom State/Civilization Subsistence: Foraging Foraging/pastoralism Horticulture or (rarely) foraging Agriculture Mobility: High Medium/cyclic Low Lowest Food storage: Little: days to months Little: weeks to months Medium: seasons to a few years High: reliance on stored foods Emphasis on property: Low but present Medium: among pastoralists, herded animals are property of individuals High: elites own special items High: major differences in material possessions by economic class Attitudes toward social ranking: Low: little stratification and generally equal access to resources for all members Medium: among pastoralists, families with more animals have higher rank High: hereditary elite class exists, but has more power to coerce than command Very high: resources allotted depend on social rank Population: 10–150 Less than 200 Low hundreds to 1,500 Tens of thousands to millions or billions Examples: Paiute of North American Great Basin, Inuit of Arctic Canada Maasai of East Africa (cattle herders), Saami of Arctic Scandinavia (reindeer herders) Maori of New Zealand, Vikings of medieval Scandinavia Ancient Egypt and Greece, Shang China, Maya (Mexico and Guatemala), United States
